If a steel containing 1.88 wt%C is cooled relatively slowly to room temperature, what is the expected weight fraction of pearlit

e in the as-cooled microstructure? Answer Format: X.XX Unit: unitless (weight fraction)
Physics

Oxana [17]3 years ago
4 0

Answer:

The answer is %pearlite = 0.06%

Explanation:

according to the exercise we have that the percentage is 1.88% C, therefore, the percentage of perlite is equal to:

%pearlite = (B*C)/(A*C) = (2-1.88)/(2-0) = 0.06%

The percentage of cementite is equal to:

%cementite = (1.88-0)/(2-0) = 0.94%

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.
OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

  • There are two magnetic and geographic poles each, north and south
  • The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
  • The magnetic north and south poles are not the same as the geographic north and south poles
  • In a compass, the needle points to the magnetic north pole
  • By convention, the magnetic north pole corresponds to the geographic south pole
  • The magnetic south pole corresponds to the geographic north pole
  • The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.

For an object starting from rest and accelerating with constant acceleration, distance traveled is proportional to the square of
natali 33 [55]

The problem states that the distance travelled (d) is directly proportional to the square of time (t^2), therefore we can write this in the form of:

d = k t^2

where k is the constant of proportionality in furlongs / s^2

 

<span>Using the 1st condition where d = 2 furlongs, t = 2 s, we calculate for the value of k:</span>

2 = k (2)^2

k = 2 / 4

k = 0.5 furlongs / s^2

The equation becomes:

d = 0.5 t^2

 

Now solving for d when t = 4:

d = 0.5 (4)^2

d = 0.5 * 16

<span>d = 8 furlongs</span>

<span>
</span>

<span>It traveled 8 furlongs for the first 4.0 seconds.</span>

A particle moving in the x direction is being acted upon by a net force f(x)=cx2, for some constant
makkiz [27]
The work-energy theorem states that the change in kinetic energy of the particle is equal to the work done on the particle:
\Delta K = W
The work done on the particle is the integral of the force on dx:
W= \int\limits^{3L}_L {F(x)} \, dx = \int\limits^{3L}_L {cx^2} \, dx = \frac{26}{3}cL^3
So, this corresponds to the change in kinetic energy of the particle.
